On my phone, so I've got to be brief - audio, audio, audio. It's the first thing I usually notice. Drop a few quid on a lav mic. They're about 30USD(or more) and will elevate your production value. In the scenes with the expert, we can barely hear your exchange of dialog. You will not regret this purchase.
The funny thing is I had the right equipment, just didn't know how to use it properly. First mistake was I forgot to check the levels before, so completely missed the fact I was only recorded on one channel. Secondly, the mic was directional, and I stupidly placed it right next to Rizwaan, but on the chair below the table. So inexperience to blame mostly. Audio is my biggest problem, and from what I've learned, seems to be the most common. Thanks for the feedback Steve, much appreciated!
